Question 2 (1 point) How far does the gravitational field of Earth extend? Q It extends to infinity. 0 It extends only as far as the orbit of the moon. 0 It extends only to a point between Earth and the moon where the two gravitational fields are equal in strength. 0 It extends only to the upper limits of Ea rth's atmosphere. Question 3 (1 point) The gravitational field strength between two objects must be zero somewhere along a long joining their centres.
